Chapter 2 Preparations
(1) Preparation before installing to the rack
The slide rail (N8143-133) for the 2U rack server is required when installing to the rack.
● Checking the inner and outer rails
Check the direction of the inner and outer rails.
Since there are markings of "Right" and "Left" on the outer rail, check the proper directions of right and left
with it. Likewise, check the directions of front and back with the markings of "Front" and "Rear."
On the inner rail, there is no marking for Front, Rear, Right or Left, so refer to the figure below to check the
each direction.
